[ale] harddrive errors

[John Wells]

OK....well....I journeyed to Circuit City today and purchased another
identical drive (Seagate 120GB Barracuda ST3120026A-RK) while erasing the
other before return.

I've only had it up for 4 hours, and already smartctl is reporting values
under RAW_VALUE for Raw_Read_Error_Rate and Seek_Error_Rate.  I'm starting
to question whether these numbers are even an accurate measure or not. 
See smartctl output below.  Thoughts?
